The base is made from two 50mm slabs of builders insulation board, glued together with Evostik Impact Adhesive. The top surface is the zero base level for the track, and will align vertically with the goods yard area of the first section. This provides a light and rigid base; the same technique was used for the first section.Other layers of board are glued to this to give elevated track and background hills, and river valleys will be cut into it. The top photo shows the initial rough cut with a print out of the track.
This is the track plan for the five foot corner section which attaches to the open end of the first town & station section. The left hand end will be an extension of the town area, then moving into open moorland with the track rising on a 2% to 3% gradient. This section was started in November 2018. The full plan is shown at the bottom of the page.
The mill building and a castle or folly have been build from card kits, ready to place on it. A low relief terrace of houses, from the rear of Archie’s Yard, will also be moved to this section.
The plywood side panels have been glued to the foam base with a building adhesive ( Everbuild StixAll) and reinforced with wooden corner mouldings. Rather than use thin MDF as the base for the track, a double layer of 3mm grey board has been used; glued together with a PVA based woodworking adhesive. The grey board was cut from A3 sheets with the joints staggered ( as in brick laying ). This was much easier to cut to shape than MDF and results in a strong but slightly flexible base; ideal for gradients. The grey board was then glued to the foam base with the building adhesive.
The usual cork strips were then glued along the track line with a generous layer of Copydex adhesive, and the track glued on top of this with just a thin layer of Copydex, weighted down with large paint cans or books till dry. Laid like this the track can easily be lifted, if required, by sliding the full blade of a snap-off blade craft knife underneath it.
The DCC bus-wires are now in place and wired to the tracks. The points servo motors have been fitted, together with micro-switches for the frog polarity and switching of isolation sections. Note that one of the servo motors has had the thickness of the operating arm increased ( two extra part arms glued to it ) so as to operate a second micro-switch for the two track isolation sections of the double track cross-over.
Further work on this section will be postponed until the base layers and track is laid for the remaining sections; so that trains can be run again.
This track plan shows the planned extension for the full layout. Each section is five foot long, total length along the back wall of 15ft. The corner section will contain an extension of the town, then with a central run over hill & dale, with bridges and long viaduct. At the right will be a return loop hidden under a hill, with a quarry and it’s siding in the front of it. Hidden sections of track are shown faint in the track plan. The highest point on the track will be about 3” above the lowest track level, which is in the town sidings, with maximum of 3% slope. This together with the depth of the foam baseboard will allow a viaduct height of about 6”; equivalent to about 75ft in the real world.
